Had Spray Foam of So Cal insulate the garage in Whittier, they were professional and explained everything before starting, really impressed with the work
They explained what type of foam they’d use and why, sprayed the crawl space in under two hours, and even answered my code questions without the usual contractor attitude
Resolved the issue of outdating insulation to help bring our heating and air bill way down and our home properly insulated year round.

I had Ram Insulation help with my attached garage project. They showed up on time with three-man crew and completed my 20' by 20' garage insulation within a day. They have done very nice and detail-oriented work and my garage looks brand new and ready for the next step.
Miguel and his team were referred to us by our HVAC vendor. We had them remove and replace the insulation in our home. Miguel, Adolfo and the crew were punctual and professional throughout the project. The entire project took 3 days and they did a great job of prepping our home, covering areas to protect and keep clean, removing the old insulation, and cleaning out any remaining debris before installing the new material. Adolfo took the time to explain what would happen during each part of the process including what things I can expect from having the work done. They were also good about the cleanup work when they finished. I already notice the difference in how much the new insulation is helping block out the heat inside my home. Hard working and dedicated crew. Would highly recommend using RAM for your home insulation needs.
Miguel’s team, Hector and Alfonso did an outstanding job of insulating our attic. They came bright and early and blew in insulation as well as laid rolls of insulation throughout our space. They were professional and courteous. They even had to deal with sharing space with a painting crew that was at our house to finish up a project. Super good folks and the insulation project was priced very competitively. Give Miguel a chance to bid for your business. You won’t regret it.

I am thoroughly impressed with the expertise and customer care. Armour Montebello Insulation provided a science-based solution, not just a product installation. Their initial diagnostic was thorough, and their crew executed the plan with precision. They were careful to protect our belongings and left the worksite cleaner than they found it. The results are undeniable: a cozier, quieter, and significantly more energy-efficient home. Highly professional and highly recommended.
I can't recommend this company enough. After other contractors provided vague proposals, Armour Montebello gave us a clear, detailed plan that made perfect sense for our Montebello home. The installation team was punctual, respectful of our property, and incredibly tidy. They worked diligently and answered all our questions. The improvement in comfort is immediate, and we've already seen a positive impact on our energy bills. A trustworthy and highly skilled local business.
Our experience with Armour Montebello Insulation was flawless from start to finish. The quote was transparent and competitive, scheduling was convenient, and the crew arrived right on time. They worked efficiently as a team, were courteous throughout, and cleaned up impeccably. The before-and-after difference in our attic and the resulting home comfort is astounding. This is a company that operates with integrity and delivers on every promise.

From quote to cleanup, everything was smooth and professional. I wish we had done this sooner!
Next level services worth every penny, thanks to this company.
Outstanding service from a company that truly brightened our home's efficiency. We had an older attic with very little insulation, and the Bright Sky team transformed it. Their quote was clear and competitive, and the installation crew worked efficiently with great attention to detail. They ensured the insulation was evenly distributed and that all vents were clear for proper airflow. The improvement in comfort is immediate—no more drafts and our HVAC system runs much less frequently. Highly recommended.

They were very easy to work with, they documented all the work. In less than a week I had someone evaluate the work needed and complete. They were also way more affordable than 2 other companies I contacted prior to them.
This company is highly professional. They are punctual, professional, and efficient in their work. They removed old attic insulation, sealed air leaks around vents and lighting, and installed new rodent-proof insulation. The courteous workers handled everything, and our house was very clean when they left. I highly recommend this company.
These guys are so amazing they show up on time. They do a good job and the price was good. I highly recommend them because they are licensed and they use all the professional tools and equipment.
